Look at the initrd, and the linuxrc script.

It probably contain some code to find the cdrom and mount it by doing something like this:

	for x in hda hdb hdc hdd                        
		do  
        		mount -t iso9660 /dev/${x} /cdrom                                         
		        if [ "$?" == "0" ]                          
		        then            
		                CDROM=${x}                          
		                break                     
		        fi          
		done    




If the Kernel support NFS, you can probably replace the first part where it looks for the CDROM with code that mount an NFS share SLAX files in it.
